Artificial Neural Networks:

Lets take an example to understand it better. Suppose we have multiple inputs x1, x2 ,x3 and x4 based upon their importance they are being multiplied by their weights β1, β2, β3,β4 and are summed together like, We add a value called bias b:

z = β1*x1 + β2*x2 + β3*x3 + β4*x4+b

Optimizing weights

β = β-α*∂j/∂β
